Netflow 3750, 3560

[thinkmoney]

Is there a way to get netflow statistics from 3750 and 3560 switches?

If not, why not, and is there any plans to do such a thing?

No you can't, you'll have to ask Cisco, I doubt it.

HTH and please rate.

Hello,

you cannot use a netflow on 3550,3560 and 3750 devices. This feature is not (and won't be) supported. I think that netflow is not implemented in hardware and CPU is too slow to software generated netflow. You can use a netflow on your upper router (border) or passive probes (see http://www.invea.cz). But you will be able to see only upstream traffic (not a traffic between individual ports).

Kind regards
